Frank Raymond Allchin FBA (9 July 1923 – 4 June 2010) with his wife, Bridget Allchin FSA (1927–Present), represent one of the most influential British partnerships in the post-Independence study of South Asian archaeology. Producing a large body of scholarship ranging from archaeological excavations, ethnoarchaeology as well as epigraphy and linguistics, the Allchins made their work and that of others highly accessible through a series of sole, joint and edited publications. Seminal works include The Birth of Indian Civilisation (1968), which was later superseded only by their books The Rise of Indian Civilisation in India and Pakistan (1982) and The Archaeology of Early Historic South Asia (1995).
The Allchins were also pivotal in promoting and facilitating the study of South Asian archaeology in Europe as well as within the Subcontinent. In the 1970s, aware of the fragmented nature of South Asian scholarship across Europe and seeking to broaden the capacity that was at the time possible and available within Britain, the Allchins, together with colleagues from Europe, created a biannual platform for South Asian archaeologists, numismatists, epigraphers and historians of art and architecture to exchange information from current research. Forming the European Association of South Asian Archaeologists, the Allchins organised the first meeting, which was held at Churchill College in Cambridge in 1971.
In reaction to the lack of institutions, teaching posts or funds devoted to the promotion of popular or scholarly interest in South and Central Asia, the Allchins, along with Professor Sir Harold Bailey, Professor Johanna van Lohuizen de Leeuw and Dr Jan van Lohuizen, founded the Ancient and Indian Iran Trust in Cambridge in 1978. The Trust aimed to support and provide a focal point where scholars and members of the public with interests in the cultures of these geographic regions could meet and use its unique library, substantially composed of the collections of its founders. The Trust also organised funds to facilitate Indian and Pakistani visiting fellowships, which included highly distinguished scholars including Dilip Chakrabari, Ravi Korisettar, K. Krishnan, V. N. Misra, Lolita Nehru, K. Paddaya, Gautam Sengupta and Vasant Shinde.
The legacy of the Allchins, and the Trust that they helped found, continues to support the promotion of South Asian scholarship. In December 2013, the first Annual Allchin Symposium, named in their honour, was held at the Trust. Established to commemorate their work and outstanding contribution to the development of South Asian studies in the United Kingdom, the Symposium brings together established lecturers, post-doctoral researchers and PhD students working in South Asian Archaeology, History and the History of Art and Architecture, providing a forum for the presentation and discussion of current research. Amongst other collections, the Ancient India and Iran Trust also houses the Allchin archive, comprising the photographic slide collection of both Allchins and the meticulous work diaries which Raymond kept during each of his field seasons, offering great potential to scholars of South Asian archaeology.
